Trial Summary

What is the purpose of this trial?

This trial will study how doing a mental task affects muscle fatigue during exercise. It involves general individuals and aims to see if mental effort changes how tired muscles get.

Do I need to stop taking my current medications for the trial?

The trial information does not specify whether you need to stop taking your current medications.

What data supports the effectiveness of the treatment Cognitive Task, Cognitive Training, Cognitive Remediation, Cognitive Rehabilitation, Cognitive Stimulation Therapy?

Research shows that cognitive rehabilitation, which includes cognitive training and remediation, is effective in improving attention, memory, and other cognitive functions in patients with brain injuries and multiple sclerosis. Studies have demonstrated significant improvements in cognitive performance and everyday behaviors after using computer-assisted cognitive training programs. ^{1 2 3 4 5}

Is cognitive training safe for humans?

Cognitive training, used in various conditions like brain injury and cancer, is generally safe for humans. Some studies noted minor side effects such as mental fatigue, headache, and eye irritation, but overall, participants showed improved cognitive functions without significant safety concerns. ^{1 6 7 8 9}

How does this treatment for cognitive task performance during fatigue differ from other treatments?

This treatment is unique because it focuses on cognitive training using a novel game called 'Decoder' on an iPad, which enhances attention without medication. Unlike traditional drug treatments like methylphenidate, which is used for mental fatigue after brain injury, this approach is non-pharmacological and aims to improve sustained attention through engaging and motivating tasks. ^{10 11 12 13 14}

Findings from Research

Cognitive rehabilitation (CR) has been identified as a potentially effective method for treating cognitive impairments, particularly memory and attention issues, in patients with epilepsy, based on a review of 18 studies.

A holistic approach to CR was found to be more beneficial than selective interventions, highlighting the importance of treatment modalities and outcome measures in clinical practice and research for epilepsy patients.

Cognitive rehabilitation is a structured intervention that helps individuals recover cognitive skills after a brain injury, using tailored treatment plans based on thorough neuropsychological assessments.

It has been shown to be effective for a range of cognitive impairments, from mild to severe injuries, and can lead to significant improvements in cognitive abilities and overall psychosocial functioning at any time after the injury.

Intellectual Function Training (IFT) is an occupational therapy method designed for cognitive retraining in patients with brain damage, focusing on enhancing various intellectual abilities such as visual perception, memory, and logical reasoning.

The IFT program involves systematic, individualized daily treatment over 2-4 months, utilizing comprehensive training materials based on neuropsychological and pedagogical principles to effectively remediate cognitive dysfunction.

Computerized cognitive training (CCT) shows strong evidence for improving processing speed in individuals with multiple sclerosis and moderate evidence for enhancing memory in both multiple sclerosis and brain tumor patients, based on a systematic review of 96 studies.

Despite the large number of studies on CCT, only 14 provided high-quality evidence (Level 1), and most outcomes focused on mental functions rather than activities or participation, suggesting a need for more comprehensive measures to assess the full impact of CCT.

A follow-up study over 5.5 years showed that methylphenidate significantly improved mental fatigue, depression, anxiety, and processing speed in patients with mild traumatic brain injury (TBI), compared to those who did not receive the treatment.

Discontinuing methylphenidate led to a significant worsening of symptoms, indicating that ongoing treatment may be necessary for sustained improvement in cognitive function after TBI.

Cognitive remediation (CR) has been shown to effectively improve cognitive deficits in individuals with psychiatric disorders, which can enhance daily functioning and potentially influence the course of their illness.

To optimize CR interventions, it is recommended that they be engaging and motivating, utilize positive emotional stimuli, and connect training tasks to real-life situations, while also considering the potential positive effects on overall symptoms.

Cognitive training using the game 'Decoder' significantly improved sustained visual attention in 75 healthy young adults compared to control groups, as measured by the Cambridge Neuropsychological Test Automated Battery.

Participants who played Decoder reported higher enjoyment, motivation, and alertness, suggesting that this non-pharmacological approach could be beneficial for enhancing attention, potentially extending its use to individuals with attention-related disorders.
